OCCUPANT RESTRAINT SYSTEMS The "AIRBAG ON" and "AIRBAG OFF" indicator lights will be illuminated when the ignition switch is in the "ON" position and a child or child restraint system is in the front passenger seat (see table−condition 2). This indicates that in the event of a severe frontal or passenger's side impact, the front passenger airbag and side airbag on the front passenger seat are deactivated and will not deploy. If the front passenger occupant classification system determines that a person of adult size sits in the front passenger seat but the "AIRBAG OFF" indicator light is illuminated, one of the following is likely to have occurred: D The rear passenger lifts the front passenger seat cushion with their legs. D Objects are placed under the front passenger seat. D A front passenger seat seatback is in contact with a rear seat. To ensure the system correctly detects an adult sitting in the front passenger seat, make sure the above do not happen. Make sure the "AIRBAG ON" indicator light is illuminated when an adult sits in the front passenger seat. If the "AIRBAG OFF" indicator light is illuminated, ask the passenger to sit up straight, well back in the seat, and with the seat belt worn correctly. If the "AIRBAG OFF" indicator light still remains illuminated, either ask the passenger to move to the rear seat, or if that is not possible, move the front passenger seat fully rearward. The SRS warning light and "AIRBAG OFF" indicator light will be illuminated if there is a malfunction in the front passenger occupant classification system. The "AIRBAG ON" and "AIRBAG OFF" indicator light will be initially illuminated when the ignition switch is turned to the "ON" position. It will remain for about four seconds and then go off. After about two seconds, the front passenger occupant classification system operates and judges whether to turn the indicator light on or not. 194
